*ToKA all whom it 'may concern):

Be it known that LFRANK COLEMAN, a citiz'en of the UnitedStates of'America, residing at Bridgewater, in the Province of Nova Scotia, `Cana'da ,hav. invented new and usefulImprovements in Rail-Ties, of .which the following is a specification.I My invention relates to railway-ties; and its primary object is to produce a comparatively simple inexpensive device of this charractice will be exceedingly strong and durable and which will firmly support the railway-rails. With the above and other objects in view the invention consists 'in the construction', combination, and arrangement of parts hereinafter fully described, claimed, and illustrated in the accompanying drawings, which disclose the preferred form of my invention, and wherein- Figure 1 is a top plan view of/a fragmentary portion of a railway constructed with v ties made in accordance with my invention.

Fig. 2 is a side elevation of one of the ties. Fig. 3 is a central horizontal sectional view thereof. Fig. 4 is a detail perspectiveview of one of the side plates of the tie. Fig. 5 is a detail perspective view of one of the spacingblocks, and Fig. 6 is an end View of the tie.

Referring to the drawings by reference, 1 1 designate side plates, which are preferably constructed of steel and which have their longitudinal edges turned downwardly to provide horizontal flanges 2 2, whereby the plates are provided with hanneled portions. These plates are adapted to be secured together in endwise osition and are spaced apart by means of) blocks V4. The blocks have their sides cut away or mortised to produce reduced portl ons 5, adapted to fit in the channels 3 of the plates 1 and are of a thickness equal to thi transverse extentof the plates 1, whereby t`1eir'u per edges lie Hush with the upper surfaces o the flanges 2, as is clearly illustrated in Fig. 6 of the drawings. The blocks not only space the plates 1 1, but also receive the spikes 6 for securing the rails in applied position u on the ties, and they are secured in applie lposition-by bolts 7 or their 'equivalent and positioned from the ends of the plates 1 inwardly a sufficient distance to4 permit of the raiIsbeing spaced apart the ordinary gage.

. The slpaos between the blocks.l and be-` tween t e outer ends-thereof and the extremities of the lates 1 arelled with cement 8 or other suita le composition.

The blocks are impregnated with a preservative compound for preventing decay and attacks of msects and worms.

The several elements of the Vties are assembled in the following manner: The plates are I first arranged in parallel relation, then Vthe blocks have their reduced portions 5 positioned between the `flanges 2 2, and then the plates and blocks are firmly united by bolts 7, passing through openings 9 in the plates 1 and similar openin s 10 in the blocks 4. After the plates and locks have been thus secured together the cement or concrete 8 is applied in any preferred manner.

From the fore oing description, taken in connection with t e accom anying drawings, the construction and modie of o eration of the inventionfwill be understoo further description.

Changes in the form, proportions, and minor details of construction may be made within the scope of the invention without de arting from the spirit or sacrificing any o the advantages thereof.

Havin thus fully described the invention,

Without a 4what is c aimed as new is- In testimony whereof I affix my signature in presence of two witnesses.

FRANK COLEMAN.
